Now to today’s Sudoku. There was a recent series of 8 on Krtek’s Cup called Between Walls. This was a slightly varied form of Between 1 and 9 Sudoku, with different numbers forming the walls. However, the numbers were given in the rules, or were red to let you know which they are. I had the thought then that it might be fun without knowing what the numbers are and decided to give it a try. The result is below. I believe it isn’t too tricky, but could have a narrow path which is difficult to see at some points. The hard rating is more for that than the logic involved.

Rules – Follow regular Sudoku rules. Additionally, the clues outside the grid give the sum of numbers that are between the walls in that row or column. The 2 numbers that form these walls are unknown but constant throughout the puzzle (and need to be determined by the solver).
